| Outline of Final Research Achievements |
The one-pot production of highly unsaturated fatty acid (PUFA) and astaxanthin (Atx) from the culture of a marine microorganism, Thrautochitorium sp. CHN-1 on food wastes with a reciprocating shaker or an small external loop airlift bubble column reactor were investigated. It was found that hexose such as glucose in Okara-enzyme hydrolysates have the great potential as a fermentation carbon substrates. A rice bran, Sake lees, and squeezed residues of fruit juices, as well as Okara hydrolysates, were also found to be available for the present one-pot production. A high content of Atx in the carotenoids was obtained under forced-air culture conditions.
